[Pacemaker] iscsi migration to slow (disk errors) tune pacemaker or open-iscsi?

[Jelle de Jong]

Hello everybody,

I started a nice new tread for this,

I seem to got a working drbd/iscsi pacemaker setup that behaves as
expected when nodes go done/up or resources are moved. (only got some
issues with the high verbosity in syslog, but that is unrelated to this
thread)

When resources are migrated on the crm nods, the open-iscsi client side
will get disk errors and the running kvm quest will get in trouble, this
only seems to happen when there is a lot of disk activity on the kvm
quest, (higher loads on all systems)

Would somebody give some advice on either optimising my pacemaker
configuration or tune my open-iscsi (timeouts?) some examples or good
documentation URL's would be appreciated.

With kind regards,
